At Stapleton's show in Buffalo, N.Y., Lambert casually strolled onto the stage prior to the start of "Fire Away;" the crowd quickly caught on, greeting her with loud cheers as Stapleton's wife Morgane welcomed her. The two women added harmonies throughout "Fire Away," with fans singing and cheering along, but near the end of the song, the Stapletons ceded lead vocals to Lambert. The audience roared with approval as Lambert finished off the tune, earning a hug from Morgane Stapleton and words of praise from Chris Stapleton.
